77 # NEW FEATURES
78
79 * Merged with **youtube-dl v2021.12.17+ [commit/2dd6c6e](https://github.com/ytdl-org/youtube-dl/commit/2dd6c6e)** ([exceptions](https://github.com/yt-dlp/yt-dlp/issues/21)) and **youtube-dlc v2020.11.11-3+ [commit/f9401f2](https://github.com/blackjack4494/yt-dlc/commit/f9401f2a91987068139c5f757b12fc711d4c0cee)**: You get all the features and patches of [youtube-dlc](https://github.com/blackjack4494/yt-dlc) in addition to the latest [youtube-dl](https://github.com/ytdl-org/youtube-dl)
80
81 * **[SponsorBlock Integration](#sponsorblock-options)**: You can mark/remove sponsor sections in YouTube videos by utilizing the [SponsorBlock](https://sponsor.ajay.app) API
82
83 * **[Format Sorting](#sorting-formats)**: The default format sorting options have been changed so that higher resolution and better codecs will be now preferred instead of simply using larger bitrate. Furthermore, you can now specify the sort order using `-S`. This allows for much easier format selection than what is possible by simply using `--format` ([examples](#format-selection-examples))
84
85 * **Merged with animelover1984/youtube-dl**: You get most of the features and improvements from [animelover1984/youtube-dl](https://github.com/animelover1984/youtube-dl) including `--write-comments`, `BiliBiliSearch`, `BilibiliChannel`, Embedding thumbnail in mp4/ogg/opus, playlist infojson etc. Note that NicoNico livestreams are not available. See [#31](https://github.com/yt-dlp/yt-dlp/pull/31) for details.
86
87 * **YouTube improvements**:
88 * Supports Clips, Stories (`ytstories:<channel UCID>`), Search (including filters)**\***, YouTube Music Search, Channel-specific search, Search prefixes (`ytsearch:`, `ytsearchdate:`)**\***, Mixes, YouTube Music Albums/Channels ([except self-uploaded music](https://github.com/yt-dlp/yt-dlp/issues/723)), and Feeds (`:ytfav`, `:ytwatchlater`, `:ytsubs`, `:ythistory`, `:ytrec`, `:ytnotif`)
89 * Fix for [n-sig based throttling](https://github.com/ytdl-org/youtube-dl/issues/29326) **\***
90 * Supports some (but not all) age-gated content without cookies
91 * Download livestreams from the start using `--live-from-start` (*experimental*)
92 * `255kbps` audio is extracted (if available) from YouTube Music when premium cookies are given
93 * Channel URLs download all uploads of the channel, including shorts and live
94
95 * **Cookies from browser**: Cookies can be automatically extracted from all major web browsers using `--cookies-from-browser BROWSER[+KEYRING][:PROFILE][::CONTAINER]`
96
97 * **Download time range**: Videos can be downloaded partially based on either timestamps or chapters using `--download-sections`
98
99 * **Split video by chapters**: Videos can be split into multiple files based on chapters using `--split-chapters`
100
101 * **Multi-threaded fragment downloads**: Download multiple fragments of m3u8/mpd videos in parallel. Use `--concurrent-fragments` (`-N`) option to set the number of threads used
102
103 * **Aria2c with HLS/DASH**: You can use `aria2c` as the external downloader for DASH(mpd) and HLS(m3u8) formats
104
105 * **New and fixed extractors**: Many new extractors have been added and a lot of existing ones have been fixed. See the [changelog](Changelog.md) or the [list of supported sites](supportedsites.md)
106
107 * **New MSOs**: Philo, Spectrum, SlingTV, Cablevision, RCN etc.
108
109 * **Subtitle extraction from manifests**: Subtitles can be extracted from streaming media manifests. See [commit/be6202f](https://github.com/yt-dlp/yt-dlp/commit/be6202f12b97858b9d716e608394b51065d0419f) for details
110
111 * **Multiple paths and output templates**: You can give different [output templates](#output-template) and download paths for different types of files. You can also set a temporary path where intermediary files are downloaded to using `--paths` (`-P`)
112
113 * **Portable Configuration**: Configuration files are automatically loaded from the home and root directories. See [CONFIGURATION](#configuration) for details
114
115 * **Output template improvements**: Output templates can now have date-time formatting, numeric offsets, object traversal etc. See [output template](#output-template) for details. Even more advanced operations can also be done with the help of `--parse-metadata` and `--replace-in-metadata`
116
117 * **Other new options**: Many new options have been added such as `--alias`, `--print`, `--concat-playlist`, `--wait-for-video`, `--retry-sleep`, `--sleep-requests`, `--convert-thumbnails`, `--force-download-archive`, `--force-overwrites`, `--break-on-reject` etc
118
119 * **Improvements**: Regex and other operators in `--format`/`--match-filter`, multiple `--postprocessor-args` and `--downloader-args`, faster archive checking, more [format selection options](#format-selection), merge multi-video/audio, multiple `--config-locations`, `--exec` at different stages, etc
120
121 * **Plugins**: Extractors and PostProcessors can be loaded from an external file. See [plugins](#plugins) for details
122
123 * **Self updater**: The releases can be updated using `yt-dlp -U`, and downgraded using `--update-to` if required
124
125 * **Nightly builds**: [Automated nightly builds](#update-channels) can be used with `--update-to nightly`
126
127 See [changelog](Changelog.md) or [commits](https://github.com/yt-dlp/yt-dlp/commits) for the full list of changes
128
129 Features marked with a **\*** have been back-ported to youtube-dl
130
131 ### Differences in default behavior
132
133 Some of yt-dlp's default options are different from that of youtube-dl and youtube-dlc:
134
135 * yt-dlp supports only [Python 3.7+](## "Windows 7"), and *may* remove support for more versions as they [become EOL](https://devguide.python.org/versions/#python-release-cycle); while [youtube-dl still supports Python 2.6+ and 3.2+](https://github.com/ytdl-org/youtube-dl/issues/30568#issue-1118238743)
136 * The options `--auto-number` (`-A`), `--title` (`-t`) and `--literal` (`-l`), no longer work. See [removed options](#Removed) for details
137 * `avconv` is not supported as an alternative to `ffmpeg`
138 * yt-dlp stores config files in slightly different locations to youtube-dl. See [CONFIGURATION](#configuration) for a list of correct locations
139 * The default [output template](#output-template) is `%(title)s [%(id)s].%(ext)s`. There is no real reason for this change. This was changed before yt-dlp was ever made public and now there are no plans to change it back to `%(title)s-%(id)s.%(ext)s`. Instead, you may use `--compat-options filename`
140 * The default [format sorting](#sorting-formats) is different from youtube-dl and prefers higher resolution and better codecs rather than higher bitrates. You can use the `--format-sort` option to change this to any order you prefer, or use `--compat-options format-sort` to use youtube-dl's sorting order
141 * The default format selector is `bv*+ba/b`. This means that if a combined video + audio format that is better than the best video-only format is found, the former will be preferred. Use `-f bv+ba/b` or `--compat-options format-spec` to revert this
142 * Unlike youtube-dlc, yt-dlp does not allow merging multiple audio/video streams into one file by default (since this conflicts with the use of `-f bv*+ba`). If needed, this feature must be enabled using `--audio-multistreams` and `--video-multistreams`. You can also use `--compat-options multistreams` to enable both
143 * `--no-abort-on-error` is enabled by default. Use `--abort-on-error` or `--compat-options abort-on-error` to abort on errors instead
144 * When writing metadata files such as thumbnails, description or infojson, the same information (if available) is also written for playlists. Use `--no-write-playlist-metafiles` or `--compat-options no-playlist-metafiles` to not write these files
145 * `--add-metadata` attaches the `infojson` to `mkv` files in addition to writing the metadata when used with `--write-info-json`. Use `--no-embed-info-json` or `--compat-options no-attach-info-json` to revert this
146 * Some metadata are embedded into different fields when using `--add-metadata` as compared to youtube-dl. Most notably, `comment` field contains the `webpage_url` and `synopsis` contains the `description`. You can [use `--parse-metadata`](#modifying-metadata) to modify this to your liking or use `--compat-options embed-metadata` to revert this
147 * `playlist_index` behaves differently when used with options like `--playlist-reverse` and `--playlist-items`. See [#302](https://github.com/yt-dlp/yt-dlp/issues/302) for details. You can use `--compat-options playlist-index` if you want to keep the earlier behavior
148 * The output of `-F` is listed in a new format. Use `--compat-options list-formats` to revert this
149 * Live chats (if available) are considered as subtitles. Use `--sub-langs all,-live_chat` to download all subtitles except live chat. You can also use `--compat-options no-live-chat` to prevent any live chat/danmaku from downloading
150 * YouTube channel URLs download all uploads of the channel. To download only the videos in a specific tab, pass the tab's URL. If the channel does not show the requested tab, an error will be raised. Also, `/live` URLs raise an error if there are no live videos instead of silently downloading the entire channel. You may use `--compat-options no-youtube-channel-redirect` to revert all these redirections
151 * Unavailable videos are also listed for YouTube playlists. Use `--compat-options no-youtube-unavailable-videos` to remove this
152 * The upload dates extracted from YouTube are in UTC [when available](https://github.com/yt-dlp/yt-dlp/blob/89e4d86171c7b7c997c77d4714542e0383bf0db0/yt_dlp/extractor/youtube.py#L3898-L3900). Use `--compat-options no-youtube-prefer-utc-upload-date` to prefer the non-UTC upload date.
153 * If `ffmpeg` is used as the downloader, the downloading and merging of formats happen in a single step when possible. Use `--compat-options no-direct-merge` to revert this
154 * Thumbnail embedding in `mp4` is done with mutagen if possible. Use `--compat-options embed-thumbnail-atomicparsley` to force the use of AtomicParsley instead
155 * Some private fields such as filenames are removed by default from the infojson. Use `--no-clean-infojson` or `--compat-options no-clean-infojson` to revert this
156 * When `--embed-subs` and `--write-subs` are used together, the subtitles are written to disk and also embedded in the media file. You can use just `--embed-subs` to embed the subs and automatically delete the separate file. See [#630 (comment)](https://github.com/yt-dlp/yt-dlp/issues/630#issuecomment-893659460) for more info. `--compat-options no-keep-subs` can be used to revert this
157 * `certifi` will be used for SSL root certificates, if installed. If you want to use system certificates (e.g. self-signed), use `--compat-options no-certifi`
158 * yt-dlp's sanitization of invalid characters in filenames is different/smarter than in youtube-dl. You can use `--compat-options filename-sanitization` to revert to youtube-dl's behavior
159 * yt-dlp tries to parse the external downloader outputs into the standard progress output if possible (Currently implemented: [~~aria2c~~](https://github.com/yt-dlp/yt-dlp/issues/5931)). You can use `--compat-options no-external-downloader-progress` to get the downloader output as-is
160
161 For ease of use, a few more compat options are available:
162
163 * `--compat-options all`: Use all compat options (Do NOT use)
164 * `--compat-options youtube-dl`: Same as `--compat-options all,-multistreams`
165 * `--compat-options youtube-dlc`: Same as `--compat-options all,-no-live-chat,-no-youtube-channel-redirect`
166 * `--compat-options 2021`: Same as `--compat-options 2022,no-certifi,filename-sanitization,no-youtube-prefer-utc-upload-date`
167 * `--compat-options 2022`: Same as `--compat-options no-external-downloader-progress`. Use this to enable all future compat options

180 <!-- MANPAGE: END EXCLUDED SECTION -->
181
182 You can install yt-dlp using [the binaries](#release-files), [PIP](https://pypi.org/project/yt-dlp) or one using a third-party package manager. See [the wiki](https://github.com/yt-dlp/yt-dlp/wiki/Installation) for detailed instructions
183
184
185 ## UPDATE
186 You can use `yt-dlp -U` to update if you are [using the release binaries](#release-files)
187
188 If you [installed with PIP](https://github.com/yt-dlp/yt-dlp/wiki/Installation#with-pip), simply re-run the same command that was used to install the program
189
190 For other third-party package managers, see [the wiki](https://github.com/yt-dlp/yt-dlp/wiki/Installation#third-party-package-managers) or refer their documentation
191
192 <a id="update-channels"/>
193
194 There are currently two release channels for binaries, `stable` and `nightly`.
195 `stable` releases are what the program will update to by default, and have had many of their changes tested by users of the master branch.
196 `nightly` releases are built after each push to the master branch, and will have the most recent fixes and additions, but also have the potential for bugs.
197 The latest `nightly` is available as a [pre-release from this repository](https://github.com/yt-dlp/yt-dlp/releases/tag/nightly), and all `nightly` releases are [archived in their own repo](https://github.com/yt-dlp/yt-dlp-nightly-builds/releases).
198
199 When using `--update`/`-U`, a release binary will only update to its current channel.
200 This release channel can be changed by using the `--update-to` option. `--update-to` can also be used to upgrade or downgrade to specific tags from a channel.
201
202 Example usage:
203 * `yt-dlp --update-to nightly` change to `nightly` channel and update to its latest release
204 * `yt-dlp --update-to stable@2023.02.17` upgrade/downgrade to release to `stable` channel tag `2023.02.17`
205 * `yt-dlp --update-to 2023.01.06` upgrade/downgrade to tag `2023.01.06` if it exists on the current channel

244 ## DEPENDENCIES
245 Python versions 3.7+ (CPython and PyPy) are supported. Other versions and implementations may or may not work correctly.
246
247 <!-- Python 3.5+ uses VC++14 and it is already embedded in the binary created
248 <!x-- https://www.microsoft.com/en-us/download/details.aspx?id=26999 --x>
249 On windows, [Microsoft Visual C++ 2010 SP1 Redistributable Package (x86)](https://download.microsoft.com/download/1/6/5/165255E7-1014-4D0A-B094-B6A430A6BFFC/vcredist_x86.exe) is also necessary to run yt-dlp. You probably already have this, but if the executable throws an error due to missing `MSVCR100.dll` you need to install it manually.
250 -->
251
252 While all the other dependencies are optional, `ffmpeg` and `ffprobe` are highly recommended
253

257
258 There are bugs in ffmpeg that causes various issues when used alongside yt-dlp. Since ffmpeg is such an important dependency, we provide [custom builds](https://github.com/yt-dlp/FFmpeg-Builds#ffmpeg-static-auto-builds) with patches for some of these issues at [yt-dlp/FFmpeg-Builds](https://github.com/yt-dlp/FFmpeg-Builds). See [the readme](https://github.com/yt-dlp/FFmpeg-Builds#patches-applied) for details on the specific issues solved by these builds

286
287 To use or redistribute the dependencies, you must agree to their respective licensing terms.
288
289 The standalone release binaries are built with the Python interpreter and the packages marked with **\*** included.
290
291 If you do not have the necessary dependencies for a task you are attempting, yt-dlp will warn you. All the currently available dependencies are visible at the top of the `--verbose` output
292
293
294 ## COMPILE
295
296 ### Standalone PyInstaller Builds
297 To build the standalone executable, you must have Python and `pyinstaller` (plus any of yt-dlp's [optional dependencies](#dependencies) if needed). Once you have all the necessary dependencies installed, simply run `pyinst.py`. The executable will be built for the same architecture (x86/ARM, 32/64 bit) as the Python used.
298
299 python3 -m pip install -U pyinstaller -r requirements.txt
300 python3 devscripts/make_lazy_extractors.py
301 python3 pyinst.py
302
303 On some systems, you may need to use `py` or `python` instead of `python3`.
304
305 `pyinst.py` accepts any arguments that can be passed to `pyinstaller`, such as `--onefile/-F` or `--onedir/-D`, which is further [documented here](https://pyinstaller.org/en/stable/usage.html#what-to-generate).
306
307 **Note**: Pyinstaller versions below 4.4 [do not support](https://github.com/pyinstaller/pyinstaller#requirements-and-tested-platforms) Python installed from the Windows store without using a virtual environment.
308
309 **Important**: Running `pyinstaller` directly **without** using `pyinst.py` is **not** officially supported. This may or may not work correctly.
310
311 ### Platform-independent Binary (UNIX)
312 You will need the build tools `python` (3.7+), `zip`, `make` (GNU), `pandoc`\* and `pytest`\*.
313
314 After installing these, simply run `make`.
315
316 You can also run `make yt-dlp` instead to compile only the binary without updating any of the additional files. (The build tools marked with **\*** are not needed for this)
317
318 ### Standalone Py2Exe Builds (Windows)
319
320 While we provide the option to build with [py2exe](https://www.py2exe.org), it is recommended to build [using PyInstaller](#standalone-pyinstaller-builds) instead since the py2exe builds **cannot contain `pycryptodomex`/`certifi` and needs VC++14** on the target computer to run.
321
322 If you wish to build it anyway, install Python and py2exe, and then simply run `setup.py py2exe`
323
324 py -m pip install -U py2exe -r requirements.txt
325 py devscripts/make_lazy_extractors.py
326 py setup.py py2exe
327
328 ### Related scripts
329
330 * **`devscripts/update-version.py`** - Update the version number based on current date.
331 * **`devscripts/set-variant.py`** - Set the build variant of the executable.
332 * **`devscripts/make_changelog.py`** - Create a markdown changelog using short commit messages and update `CONTRIBUTORS` file.
333 * **`devscripts/make_lazy_extractors.py`** - Create lazy extractors. Running this before building the binaries (any variant) will improve their startup performance. Set the environment variable `YTDLP_NO_LAZY_EXTRACTORS=1` if you wish to forcefully disable lazy extractor loading.
334
335 Note: See their `--help` for more info.
336
337 ### Forking the project
338 If you fork the project on GitHub, you can run your fork's [build workflow](.github/workflows/build.yml) to automatically build the selected version(s) as artifacts. Alternatively, you can run the [release workflow](.github/workflows/release.yml) or enable the [nightly workflow](.github/workflows/release-nightly.yml) to create full (pre-)releases.

340 # USAGE AND OPTIONS
341
342 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
343 yt-dlp [OPTIONS] [--] URL [URL...]
344
345 `Ctrl+F` is your friend :D
346 <!-- MANPAGE: END EXCLUDED SECTION -->
347
348 <!-- Auto generated -->
349 ## General Options:
350 -h, --help Print this help text and exit
351 --version Print program version and exit
352 -U, --update Update this program to the latest version
353 --no-update Do not check for updates (default)
354 --update-to [CHANNEL]@[TAG] Upgrade/downgrade to a specific version.
355 CHANNEL and TAG defaults to "stable" and
356 "latest" respectively if ommited; See
357 "UPDATE" for details. Supported channels:
358 stable, nightly
359 -i, --ignore-errors Ignore download and postprocessing errors.
360 The download will be considered successful
361 even if the postprocessing fails
362 --no-abort-on-error Continue with next video on download errors;
363 e.g. to skip unavailable videos in a
364 playlist (default)
365 --abort-on-error Abort downloading of further videos if an
366 error occurs (Alias: --no-ignore-errors)
367 --dump-user-agent Display the current user-agent and exit
368 --list-extractors List all supported extractors and exit
369 --extractor-descriptions Output descriptions of all supported
370 extractors and exit
371 --use-extractors NAMES Extractor names to use separated by commas.
372 You can also use regexes, "all", "default"
373 and "end" (end URL matching); e.g. --ies
374 "holodex.*,end,youtube". Prefix the name
375 with a "-" to exclude it, e.g. --ies
376 default,-generic. Use --list-extractors for
377 a list of extractor names. (Alias: --ies)
378 --default-search PREFIX Use this prefix for unqualified URLs. E.g.
379 "gvsearch2:python" downloads two videos from
380 google videos for the search term "python".
381 Use the value "auto" to let yt-dlp guess
382 ("auto_warning" to emit a warning when
383 guessing). "error" just throws an error. The
384 default value "fixup_error" repairs broken
385 URLs, but emits an error if this is not
386 possible instead of searching
387 --ignore-config Don't load any more configuration files
388 except those given by --config-locations.
389 For backward compatibility, if this option
390 is found inside the system configuration
391 file, the user configuration is not loaded.
392 (Alias: --no-config)
393 --no-config-locations Do not load any custom configuration files
394 (default). When given inside a configuration
395 file, ignore all previous --config-locations
396 defined in the current file
397 --config-locations PATH Location of the main configuration file;
398 either the path to the config or its
399 containing directory ("-" for stdin). Can be
400 used multiple times and inside other
401 configuration files
402 --flat-playlist Do not extract the videos of a playlist,
403 only list them
404 --no-flat-playlist Extract the videos of a playlist
405 --live-from-start Download livestreams from the start.
406 Currently only supported for YouTube
407 (Experimental)
408 --no-live-from-start Download livestreams from the current time
409 (default)
410 --wait-for-video MIN[-MAX] Wait for scheduled streams to become
411 available. Pass the minimum number of
412 seconds (or range) to wait between retries
413 --no-wait-for-video Do not wait for scheduled streams (default)
414 --mark-watched Mark videos watched (even with --simulate)
415 --no-mark-watched Do not mark videos watched (default)
416 --no-colors Do not emit color codes in output (Alias:
417 --no-colours)
418 --compat-options OPTS Options that can help keep compatibility
419 with youtube-dl or youtube-dlc
420 configurations by reverting some of the
421 changes made in yt-dlp. See "Differences in
422 default behavior" for details
423 --alias ALIASES OPTIONS Create aliases for an option string. Unless
424 an alias starts with a dash "-", it is
425 prefixed with "--". Arguments are parsed
426 according to the Python string formatting
427 mini-language. E.g. --alias get-audio,-X
428 "-S=aext:{0},abr -x --audio-format {0}"
429 creates options "--get-audio" and "-X" that
430 takes an argument (ARG0) and expands to
431 "-S=aext:ARG0,abr -x --audio-format ARG0".
432 All defined aliases are listed in the --help
433 output. Alias options can trigger more
434 aliases; so be careful to avoid defining
435 recursive options. As a safety measure, each
436 alias may be triggered a maximum of 100
437 times. This option can be used multiple times
438
439 ## Network Options:
440 --proxy URL Use the specified HTTP/HTTPS/SOCKS proxy. To
441 enable SOCKS proxy, specify a proper scheme,
442 e.g. socks5://user:pass@127.0.0.1:1080/.
443 Pass in an empty string (--proxy "") for
444 direct connection
445 --socket-timeout SECONDS Time to wait before giving up, in seconds
446 --source-address IP Client-side IP address to bind to
447 -4, --force-ipv4 Make all connections via IPv4
448 -6, --force-ipv6 Make all connections via IPv6
449 --enable-file-urls Enable file:// URLs. This is disabled by
450 default for security reasons.
451
452 ## Geo-restriction:
453 --geo-verification-proxy URL Use this proxy to verify the IP address for
454 some geo-restricted sites. The default proxy
455 specified by --proxy (or none, if the option
456 is not present) is used for the actual
457 downloading
458 --geo-bypass Bypass geographic restriction via faking
459 X-Forwarded-For HTTP header (default)
460 --no-geo-bypass Do not bypass geographic restriction via
461 faking X-Forwarded-For HTTP header
462 --geo-bypass-country CODE Force bypass geographic restriction with
463 explicitly provided two-letter ISO 3166-2
464 country code
465 --geo-bypass-ip-block IP_BLOCK Force bypass geographic restriction with
466 explicitly provided IP block in CIDR notation
467
468 ## Video Selection:
469 -I, --playlist-items ITEM_SPEC Comma separated playlist_index of the items
470 to download. You can specify a range using
471 "[START]:[STOP][:STEP]". For backward
472 compatibility, START-STOP is also supported.
473 Use negative indices to count from the right
474 and negative STEP to download in reverse
475 order. E.g. "-I 1:3,7,-5::2" used on a
476 playlist of size 15 will download the items
477 at index 1,2,3,7,11,13,15
478 --min-filesize SIZE Abort download if filesize is smaller than
479 SIZE, e.g. 50k or 44.6M
480 --max-filesize SIZE Abort download if filesize is larger than
481 SIZE, e.g. 50k or 44.6M
482 --date DATE Download only videos uploaded on this date.
483 The date can be "YYYYMMDD" or in the format
484 [now|today|yesterday][-N[day|week|month|year]].
485 E.g. "--date today-2weeks" downloads only
486 videos uploaded on the same day two weeks ago
487 --datebefore DATE Download only videos uploaded on or before
488 this date. The date formats accepted is the
489 same as --date
490 --dateafter DATE Download only videos uploaded on or after
491 this date. The date formats accepted is the
492 same as --date
493 --match-filters FILTER Generic video filter. Any "OUTPUT TEMPLATE"
494 field can be compared with a number or a
495 string using the operators defined in
496 "Filtering Formats". You can also simply
497 specify a field to match if the field is
498 present, use "!field" to check if the field
499 is not present, and "&" to check multiple
500 conditions. Use a "\" to escape "&" or
501 quotes if needed. If used multiple times,
502 the filter matches if atleast one of the
503 conditions are met. E.g. --match-filter
504 !is_live --match-filter "like_count>?100 &
505 description~='(?i)\bcats \& dogs\b'" matches
506 only videos that are not live OR those that
507 have a like count more than 100 (or the like
508 field is not available) and also has a
509 description that contains the phrase "cats &
510 dogs" (caseless). Use "--match-filter -" to
511 interactively ask whether to download each
512 video
513 --no-match-filter Do not use generic video filter (default)
514 --no-playlist Download only the video, if the URL refers
515 to a video and a playlist

525 --break-on-existing Stop the download process when encountering
526 a file that is in the archive
527 --break-on-reject Stop the download process when encountering
528 a file that has been filtered out
529 --break-per-input Alters --max-downloads, --break-on-existing,
530 --break-on-reject, and autonumber to reset
531 per input URL
532 --no-break-per-input --break-on-existing and similar options
533 terminates the entire download queue

552 --retry-sleep [TYPE:]EXPR Time to sleep between retries in seconds
553 (optionally) prefixed by the type of retry
554 (http (default), fragment, file_access,
555 extractor) to apply the sleep to. EXPR can
556 be a number, linear=START[:END[:STEP=1]] or
557 exp=START[:END[:BASE=2]]. This option can be
558 used multiple times to set the sleep for the
559 different retry types, e.g. --retry-sleep
560 linear=1::2 --retry-sleep fragment:exp=1:20
561 --skip-unavailable-fragments Skip unavailable fragments for DASH,
562 hlsnative and ISM downloads (default)
563 (Alias: --no-abort-on-unavailable-fragments)

586 --no-lazy-playlist Process videos in the playlist only after
587 the entire playlist is parsed (default)
588 --xattr-set-filesize Set file xattribute ytdl.filesize with
589 expected file size
590 --hls-use-mpegts Use the mpegts container for HLS videos;
591 allowing some players to play the video
592 while downloading, and reducing the chance
593 of file corruption if download is
594 interrupted. This is enabled by default for
595 live streams
596 --no-hls-use-mpegts Do not use the mpegts container for HLS
597 videos. This is default when not downloading
598 live streams
599 --download-sections REGEX Download only chapters whose title matches

610 use it for. Currently supports native,
611 aria2c, avconv, axel, curl, ffmpeg, httpie,
612 wget. You can use this option multiple times
613 to set different downloaders for different
614 protocols. E.g. --downloader aria2c
615 --downloader "dash,m3u8:native" will use
616 aria2c for http/ftp downloads, and the
617 native downloader for dash/m3u8 downloads
618 (Alias: --external-downloader)
619 --downloader-args NAME:ARGS Give these arguments to the external
620 downloader. Specify the downloader name and
621 the arguments separated by a colon ":". For
622 ffmpeg, arguments can be passed to different
623 positions using the same syntax as
624 --postprocessor-args. You can use this
625 option multiple times to give different
626 arguments to different downloaders (Alias:
627 --external-downloader-args)
628
629 ## Filesystem Options:
630 -a, --batch-file FILE File containing URLs to download ("-" for
631 stdin), one URL per line. Lines starting
632 with "#", ";" or "]" are considered as
633 comments and ignored
634 --no-batch-file Do not read URLs from batch file (default)
635 -P, --paths [TYPES:]PATH The paths where the files should be
636 downloaded. Specify the type of file and the
637 path separated by a colon ":". All the same
638 TYPES as --output are supported.
639 Additionally, you can also provide "home"
640 (default) and "temp" paths. All intermediary
641 files are first downloaded to the temp path
642 and then the final files are moved over to
643 the home path after download is finished.
644 This option is ignored if --output is an
645 absolute path
646 -o, --output [TYPES:]TEMPLATE Output filename template; see "OUTPUT
647 TEMPLATE" for details
648 --output-na-placeholder TEXT Placeholder for unavailable fields in
649 "OUTPUT TEMPLATE" (default: "NA")
650 --restrict-filenames Restrict filenames to only ASCII characters,
651 and avoid "&" and spaces in filenames
652 --no-restrict-filenames Allow Unicode characters, "&" and spaces in
653 filenames (default)
654 --windows-filenames Force filenames to be Windows-compatible
655 --no-windows-filenames Make filenames Windows-compatible only if
656 using Windows (default)
657 --trim-filenames LENGTH Limit the filename length (excluding
658 extension) to the specified number of
659 characters
660 -w, --no-overwrites Do not overwrite any files
661 --force-overwrites Overwrite all video and metadata files. This

1134 # CONFIGURATION
1135
1136 You can configure yt-dlp by placing any supported command line option to a configuration file. The configuration is loaded from the following locations:
1137
1138 1. **Main Configuration**:
1139 * The file given by `--config-location`
1140 1. **Portable Configuration**: (Recommended for portable installations)
1141 * If using a binary, `yt-dlp.conf` in the same directory as the binary
1142 * If running from source-code, `yt-dlp.conf` in the parent directory of `yt_dlp`
1143 1. **Home Configuration**:
1144 * `yt-dlp.conf` in the home path given by `-P`
1145 * If `-P` is not given, the current directory is searched
1146 1. **User Configuration**:
1147 * `${XDG_CONFIG_HOME}/yt-dlp.conf`
1148 * `${XDG_CONFIG_HOME}/yt-dlp/config` (recommended on Linux/macOS)
1149 * `${XDG_CONFIG_HOME}/yt-dlp/config.txt`
1150 * `${APPDATA}/yt-dlp.conf`
1151 * `${APPDATA}/yt-dlp/config` (recommended on Windows)
1152 * `${APPDATA}/yt-dlp/config.txt`
1153 * `~/yt-dlp.conf`
1154 * `~/yt-dlp.conf.txt`
1155 * `~/.yt-dlp/config`
1156 * `~/.yt-dlp/config.txt`
1157
1158 See also: [Notes about environment variables](#notes-about-environment-variables)
1159 1. **System Configuration**:
1160 * `/etc/yt-dlp.conf`
1161 * `/etc/yt-dlp/config`
1162 * `/etc/yt-dlp/config.txt`
1163
1164 E.g. with the following configuration file yt-dlp will always extract the audio, not copy the mtime, use a proxy and save all videos under `YouTube` directory in your home directory:
1165 ```
1166 # Lines starting with # are comments
1167
1168 # Always extract audio
1169 -x
1170
1171 # Do not copy the mtime
1172 --no-mtime
1173
1174 # Use this proxy
1175 --proxy 127.0.0.1:3128
1176
1177 # Save all videos under YouTube directory in your home directory
1178 -o ~/YouTube/%(title)s.%(ext)s
1179 ```
1180
1181 **Note**: Options in configuration file are just the same options aka switches used in regular command line calls; thus there **must be no whitespace** after `-` or `--`, e.g. `-o` or `--proxy` but not `- o` or `-- proxy`. They must also be quoted when necessary as-if it were a UNIX shell.
1182
1183 You can use `--ignore-config` if you want to disable all configuration files for a particular yt-dlp run. If `--ignore-config` is found inside any configuration file, no further configuration will be loaded. For example, having the option in the portable configuration file prevents loading of home, user, and system configurations. Additionally, (for backward compatibility) if `--ignore-config` is found inside the system configuration file, the user configuration is not loaded.
1184
1185 ### Configuration file encoding
1186
1187 The configuration files are decoded according to the UTF BOM if present, and in the encoding from system locale otherwise.
1188
1189 If you want your file to be decoded differently, add `# coding: ENCODING` to the beginning of the file (e.g. `# coding: shift-jis`). There must be no characters before that, even spaces or BOM.
1190
1191 ### Authentication with `.netrc` file
1192
1193 You may also want to configure automatic credentials storage for extractors that support authentication (by providing login and password with `--username` and `--password`) in order not to pass credentials as command line arguments on every yt-dlp execution and prevent tracking plain text passwords in the shell command history. You can achieve this using a [`.netrc` file](https://stackoverflow.com/tags/.netrc/info) on a per-extractor basis. For that you will need to create a `.netrc` file in `--netrc-location` and restrict permissions to read/write by only you:
1194 ```
1195 touch ${HOME}/.netrc
1196 chmod a-rwx,u+rw ${HOME}/.netrc
1197 ```
1198 After that you can add credentials for an extractor in the following format, where *extractor* is the name of the extractor in lowercase:
1199 ```
1200 machine <extractor> login <username> password <password>
1201 ```
1202 E.g.
1203 ```
1204 machine youtube login myaccount@gmail.com password my_youtube_password
1205 machine twitch login my_twitch_account_name password my_twitch_password
1206 ```
1207 To activate authentication with the `.netrc` file you should pass `--netrc` to yt-dlp or place it in the [configuration file](#configuration).
1208
1209 The default location of the .netrc file is `~` (see below).
1210
1211 ### Notes about environment variables
1212 * Environment variables are normally specified as `${VARIABLE}`/`$VARIABLE` on UNIX and `%VARIABLE%` on Windows; but is always shown as `${VARIABLE}` in this documentation
1213 * yt-dlp also allow using UNIX-style variables on Windows for path-like options; e.g. `--output`, `--config-location`
1214 * If unset, `${XDG_CONFIG_HOME}` defaults to `~/.config` and `${XDG_CACHE_HOME}` to `~/.cache`
1215 * On Windows, `~` points to `${HOME}` if present; or, `${USERPROFILE}` or `${HOMEDRIVE}${HOMEPATH}` otherwise
1216 * On Windows, `${USERPROFILE}` generally points to `C:\Users\<user name>` and `${APPDATA}` to `${USERPROFILE}\AppData\Roaming`
1217
1218 # OUTPUT TEMPLATE
1219
1220 The `-o` option is used to indicate a template for the output file names while `-P` option is used to specify the path each type of file should be saved to.
1221
1222 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
1223 **tl;dr:** [navigate me to examples](#output-template-examples).
1224 <!-- MANPAGE: END EXCLUDED SECTION -->
1225
1226 The simplest usage of `-o` is not to set any template arguments when downloading a single file, like in `yt-dlp -o funny_video.flv "https://some/video"` (hard-coding file extension like this is _not_ recommended and could break some post-processing).
1227
1228 It may however also contain special sequences that will be replaced when downloading each video. The special sequences may be formatted according to [Python string formatting operations](https://docs.python.org/3/library/stdtypes.html#printf-style-string-formatting), e.g. `%(NAME)s` or `%(NAME)05d`. To clarify, that is a percent symbol followed by a name in parentheses, followed by formatting operations.
1229
1230 The field names themselves (the part inside the parenthesis) can also have some special formatting:
1231
1232 1. **Object traversal**: The dictionaries and lists available in metadata can be traversed by using a dot `.` separator; e.g. `%(tags.0)s`, `%(subtitles.en.-1.ext)s`. You can do Python slicing with colon `:`; E.g. `%(id.3:7:-1)s`, `%(formats.:.format_id)s`. Curly braces `{}` can be used to build dictionaries with only specific keys; e.g. `%(formats.:.{format_id,height})#j`. An empty field name `%()s` refers to the entire infodict; e.g. `%(.{id,title})s`. Note that all the fields that become available using this method are not listed below. Use `-j` to see such fields
1233
1234 1. **Addition**: Addition and subtraction of numeric fields can be done using `+` and `-` respectively. E.g. `%(playlist_index+10)03d`, `%(n_entries+1-playlist_index)d`
1235
1236 1. **Date/time Formatting**: Date/time fields can be formatted according to [strftime formatting](https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes) by specifying it separated from the field name using a `>`. E.g. `%(duration>%H-%M-%S)s`, `%(upload_date>%Y-%m-%d)s`, `%(epoch-3600>%H-%M-%S)s`
1237
1238 1. **Alternatives**: Alternate fields can be specified separated with a `,`. E.g. `%(release_date>%Y,upload_date>%Y|Unknown)s`
1239
1240 1. **Replacement**: A replacement value can be specified using a `&` separator. If the field is *not* empty, this replacement value will be used instead of the actual field content. This is done after alternate fields are considered; thus the replacement is used if *any* of the alternative fields is *not* empty.
1241
1242 1. **Default**: A literal default value can be specified for when the field is empty using a `|` separator. This overrides `--output-na-placeholder`. E.g. `%(uploader|Unknown)s`
1243
1244 1. **More Conversions**: In addition to the normal format types `diouxXeEfFgGcrs`, yt-dlp additionally supports converting to `B` = **B**ytes, `j` = **j**son (flag `#` for pretty-printing, `+` for Unicode), `h` = HTML escaping, `l` = a comma separated **l**ist (flag `#` for `\n` newline-separated), `q` = a string **q**uoted for the terminal (flag `#` to split a list into different arguments), `D` = add **D**ecimal suffixes (e.g. 10M) (flag `#` to use 1024 as factor), and `S` = **S**anitize as filename (flag `#` for restricted)
1245
1246 1. **Unicode normalization**: The format type `U` can be used for NFC [Unicode normalization](https://docs.python.org/3/library/unicodedata.html#unicodedata.normalize). The alternate form flag (`#`) changes the normalization to NFD and the conversion flag `+` can be used for NFKC/NFKD compatibility equivalence normalization. E.g. `%(title)+.100U` is NFKC
1247
1248 To summarize, the general syntax for a field is:
1249 ```
1250 %(name[.keys][addition][>strf][,alternate][&replacement][|default])[flags][width][.precision][length]type
1251 ```
1252
1253 Additionally, you can set different output templates for the various metadata files separately from the general output template by specifying the type of file followed by the template separated by a colon `:`. The different file types supported are `subtitle`, `thumbnail`, `description`, `annotation` (deprecated), `infojson`, `link`, `pl_thumbnail`, `pl_description`, `pl_infojson`, `chapter`, `pl_video`. E.g. `-o "%(title)s.%(ext)s" -o "thumbnail:%(title)s\%(title)s.%(ext)s"` will put the thumbnails in a folder with the same name as the video. If any of the templates is empty, that type of file will not be written. E.g. `--write-thumbnail -o "thumbnail:"` will write thumbnails only for playlists and not for video.
1254
1255 <a id="outtmpl-postprocess-note"></a>
1256
1257 **Note**: Due to post-processing (i.e. merging etc.), the actual output filename might differ. Use `--print after_move:filepath` to get the name after all post-processing is complete.

1375
1376 Each aforementioned sequence when referenced in an output template will be replaced by the actual value corresponding to the sequence name. E.g. for `-o %(title)s-%(id)s.%(ext)s` and an mp4 video with title `yt-dlp test video` and id `BaW_jenozKc`, this will result in a `yt-dlp test video-BaW_jenozKc.mp4` file created in the current directory.
1377
1378 **Note**: Some of the sequences are not guaranteed to be present since they depend on the metadata obtained by a particular extractor. Such sequences will be replaced with placeholder value provided with `--output-na-placeholder` (`NA` by default).
1379
1380 **Tip**: Look at the `-j` output to identify which fields are available for the particular URL
1381
1382 For numeric sequences you can use [numeric related formatting](https://docs.python.org/3/library/stdtypes.html#printf-style-string-formatting); e.g. `%(view_count)05d` will result in a string with view count padded with zeros up to 5 characters, like in `00042`.
1383
1384 Output templates can also contain arbitrary hierarchical path, e.g. `-o "%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s"` which will result in downloading each video in a directory corresponding to this path template. Any missing directory will be automatically created for you.
1385
1386 To use percent literals in an output template use `%%`. To output to stdout use `-o -`.
1387
1388 The current default template is `%(title)s [%(id)s].%(ext)s`.
1389
1390 In some cases, you don't want special characters such as 中, spaces, or &, such as when transferring the downloaded filename to a Windows system or the filename through an 8bit-unsafe channel. In these cases, add the `--restrict-filenames` flag to get a shorter title.
1391
1392 #### Output template examples

1428
1429 # Stream the video being downloaded to stdout
1430 $ yt-dlp -o - BaW_jenozKc
1431 ```
1432
1433 # FORMAT SELECTION
1434
1435 By default, yt-dlp tries to download the best available quality if you **don't** pass any options.
1436 This is generally equivalent to using `-f bestvideo*+bestaudio/best`. However, if multiple audiostreams is enabled (`--audio-multistreams`), the default format changes to `-f bestvideo+bestaudio/best`. Similarly, if ffmpeg is unavailable, or if you use yt-dlp to stream to `stdout` (`-o -`), the default becomes `-f best/bestvideo+bestaudio`.
1437
1438 **Deprecation warning**: Latest versions of yt-dlp can stream multiple formats to the stdout simultaneously using ffmpeg. So, in future versions, the default for this will be set to `-f bv*+ba/b` similar to normal downloads. If you want to preserve the `-f b/bv+ba` setting, it is recommended to explicitly specify it in the configuration options.
1439
1440 The general syntax for format selection is `-f FORMAT` (or `--format FORMAT`) where `FORMAT` is a *selector expression*, i.e. an expression that describes format or formats you would like to download.
1441
1442 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
1443 **tl;dr:** [navigate me to examples](#format-selection-examples).
1444 <!-- MANPAGE: END EXCLUDED SECTION -->
1445
1446 The simplest case is requesting a specific format; e.g. with `-f 22` you can download the format with format code equal to 22. You can get the list of available format codes for particular video using `--list-formats` or `-F`. Note that these format codes are extractor specific.
1447
1448 You can also use a file extension (currently `3gp`, `aac`, `flv`, `m4a`, `mp3`, `mp4`, `ogg`, `wav`, `webm` are supported) to download the best quality format of a particular file extension served as a single file, e.g. `-f webm` will download the best quality format with the `webm` extension served as a single file.
1449
1450 You can use `-f -` to interactively provide the format selector *for each video*
1451
1452 You can also use special names to select particular edge case formats:
1453
1454 - `all`: Select **all formats** separately
1455 - `mergeall`: Select and **merge all formats** (Must be used with `--audio-multistreams`, `--video-multistreams` or both)
1456 - `b*`, `best*`: Select the best quality format that **contains either** a video or an audio or both (ie; `vcodec!=none or acodec!=none`)
1457 - `b`, `best`: Select the best quality format that **contains both** video and audio. Equivalent to `best*[vcodec!=none][acodec!=none]`
1458 - `bv`, `bestvideo`: Select the best quality **video-only** format. Equivalent to `best*[acodec=none]`
1459 - `bv*`, `bestvideo*`: Select the best quality format that **contains video**. It may also contain audio. Equivalent to `best*[vcodec!=none]`
1460 - `ba`, `bestaudio`: Select the best quality **audio-only** format. Equivalent to `best*[vcodec=none]`
1461 - `ba*`, `bestaudio*`: Select the best quality format that **contains audio**. It may also contain video. Equivalent to `best*[acodec!=none]` ([Do not use!](https://github.com/yt-dlp/yt-dlp/issues/979#issuecomment-919629354))
1462 - `w*`, `worst*`: Select the worst quality format that contains either a video or an audio
1463 - `w`, `worst`: Select the worst quality format that contains both video and audio. Equivalent to `worst*[vcodec!=none][acodec!=none]`
1464 - `wv`, `worstvideo`: Select the worst quality video-only format. Equivalent to `worst*[acodec=none]`
1465 - `wv*`, `worstvideo*`: Select the worst quality format that contains video. It may also contain audio. Equivalent to `worst*[vcodec!=none]`
1466 - `wa`, `worstaudio`: Select the worst quality audio-only format. Equivalent to `worst*[vcodec=none]`
1467 - `wa*`, `worstaudio*`: Select the worst quality format that contains audio. It may also contain video. Equivalent to `worst*[acodec!=none]`
1468
1469 For example, to download the worst quality video-only format you can use `-f worstvideo`. It is however recommended not to use `worst` and related options. When your format selector is `worst`, the format which is worst in all respects is selected. Most of the time, what you actually want is the video with the smallest filesize instead. So it is generally better to use `-S +size` or more rigorously, `-S +size,+br,+res,+fps` instead of `-f worst`. See [Sorting Formats](#sorting-formats) for more details.
1470
1471 You can select the n'th best format of a type by using `best<type>.<n>`. For example, `best.2` will select the 2nd best combined format. Similarly, `bv*.3` will select the 3rd best format that contains a video stream.
1472
1473 If you want to download multiple videos, and they don't have the same formats available, you can specify the order of preference using slashes. Note that formats on the left hand side are preferred; e.g. `-f 22/17/18` will download format 22 if it's available, otherwise it will download format 17 if it's available, otherwise it will download format 18 if it's available, otherwise it will complain that no suitable formats are available for download.
1474
1475 If you want to download several formats of the same video use a comma as a separator, e.g. `-f 22,17,18` will download all these three formats, of course if they are available. Or a more sophisticated example combined with the precedence feature: `-f 136/137/mp4/bestvideo,140/m4a/bestaudio`.
1476
1477 You can merge the video and audio of multiple formats into a single file using `-f <format1>+<format2>+...` (requires ffmpeg installed); e.g. `-f bestvideo+bestaudio` will download the best video-only format, the best audio-only format and mux them together with ffmpeg.
1478
1479 **Deprecation warning**: Since the *below* described behavior is complex and counter-intuitive, this will be removed and multistreams will be enabled by default in the future. A new operator will be instead added to limit formats to single audio/video
1480
1481 Unless `--video-multistreams` is used, all formats with a video stream except the first one are ignored. Similarly, unless `--audio-multistreams` is used, all formats with an audio stream except the first one are ignored. E.g. `-f bestvideo+best+bestaudio --video-multistreams --audio-multistreams` will download and merge all 3 given formats. The resulting file will have 2 video streams and 2 audio streams. But `-f bestvideo+best+bestaudio --no-video-multistreams` will download and merge only `bestvideo` and `bestaudio`. `best` is ignored since another format containing a video stream (`bestvideo`) has already been selected. The order of the formats is therefore important. `-f best+bestaudio --no-audio-multistreams` will download only `best` while `-f bestaudio+best --no-audio-multistreams` will ignore `best` and download only `bestaudio`.
1482
1483 ## Filtering Formats
1484
1485 You can also filter the video formats by putting a condition in brackets, as in `-f "best[height=720]"` (or `-f "[filesize>10M]"`).
1486
1487 The following numeric meta fields can be used with comparisons `<`, `<=`, `>`, `>=`, `=` (equals), `!=` (not equals):
1488
1489 - `filesize`: The number of bytes, if known in advance
1490 - `filesize_approx`: An estimate for the number of bytes
1491 - `width`: Width of the video, if known
1492 - `height`: Height of the video, if known
1493 - `aspect_ratio`: Aspect ratio of the video, if known
1494 - `tbr`: Average bitrate of audio and video in KBit/s
1495 - `abr`: Average audio bitrate in KBit/s
1496 - `vbr`: Average video bitrate in KBit/s
1497 - `asr`: Audio sampling rate in Hertz
1498 - `fps`: Frame rate
1499 - `audio_channels`: The number of audio channels
1500 - `stretched_ratio`: `width:height` of the video's pixels, if not square
1501
1502 Also filtering work for comparisons `=` (equals), `^=` (starts with), `$=` (ends with), `*=` (contains), `~=` (matches regex) and following string meta fields:
1503
1504 - `url`: Video URL
1505 - `ext`: File extension
1506 - `acodec`: Name of the audio codec in use
1507 - `vcodec`: Name of the video codec in use
1508 - `container`: Name of the container format
1509 - `protocol`: The protocol that will be used for the actual download, lower-case (`http`, `https`, `rtsp`, `rtmp`, `rtmpe`, `mms`, `f4m`, `ism`, `http_dash_segments`, `m3u8`, or `m3u8_native`)
1510 - `language`: Language code
1511 - `dynamic_range`: The dynamic range of the video
1512 - `format_id`: A short description of the format
1513 - `format`: A human-readable description of the format
1514 - `format_note`: Additional info about the format
1515 - `resolution`: Textual description of width and height
1516
1517 Any string comparison may be prefixed with negation `!` in order to produce an opposite comparison, e.g. `!*=` (does not contain). The comparand of a string comparison needs to be quoted with either double or single quotes if it contains spaces or special characters other than `._-`.
1518
1519 **Note**: None of the aforementioned meta fields are guaranteed to be present since this solely depends on the metadata obtained by particular extractor, i.e. the metadata offered by the website. Any other field made available by the extractor can also be used for filtering.
1520
1521 Formats for which the value is not known are excluded unless you put a question mark (`?`) after the operator. You can combine format filters, so `-f "[height<=?720][tbr>500]"` selects up to 720p videos (or videos where the height is not known) with a bitrate of at least 500 KBit/s. You can also use the filters with `all` to download all formats that satisfy the filter, e.g. `-f "all[vcodec=none]"` selects all audio-only formats.
1522
1523 Format selectors can also be grouped using parentheses; e.g. `-f "(mp4,webm)[height<480]"` will download the best pre-merged mp4 and webm formats with a height lower than 480.
1524
1525 ## Sorting Formats
1526
1527 You can change the criteria for being considered the `best` by using `-S` (`--format-sort`). The general format for this is `--format-sort field1,field2...`.
1528
1529 The available fields are:
1530
1531 - `hasvid`: Gives priority to formats that have a video stream
1532 - `hasaud`: Gives priority to formats that have an audio stream
1533 - `ie_pref`: The format preference
1534 - `lang`: The language preference
1535 - `quality`: The quality of the format
1536 - `source`: The preference of the source
1537 - `proto`: Protocol used for download (`https`/`ftps` > `http`/`ftp` > `m3u8_native`/`m3u8` > `http_dash_segments`> `websocket_frag` > `mms`/`rtsp` > `f4f`/`f4m`)
1538 - `vcodec`: Video Codec (`av01` > `vp9.2` > `vp9` > `h265` > `h264` > `vp8` > `h263` > `theora` > other)
1539 - `acodec`: Audio Codec (`flac`/`alac` > `wav`/`aiff` > `opus` > `vorbis` > `aac` > `mp4a` > `mp3` > `ac4` > `eac3` > `ac3` > `dts` > other)
1540 - `codec`: Equivalent to `vcodec,acodec`
1541 - `vext`: Video Extension (`mp4` > `mov` > `webm` > `flv` > other). If `--prefer-free-formats` is used, `webm` is preferred.
1542 - `aext`: Audio Extension (`m4a` > `aac` > `mp3` > `ogg` > `opus` > `webm` > other). If `--prefer-free-formats` is used, the order changes to `ogg` > `opus` > `webm` > `mp3` > `m4a` > `aac`
1543 - `ext`: Equivalent to `vext,aext`
1544 - `filesize`: Exact filesize, if known in advance
1545 - `fs_approx`: Approximate filesize calculated from the manifests
1546 - `size`: Exact filesize if available, otherwise approximate filesize
1547 - `height`: Height of video
1548 - `width`: Width of video
1549 - `res`: Video resolution, calculated as the smallest dimension.
1550 - `fps`: Framerate of video
1551 - `hdr`: The dynamic range of the video (`DV` > `HDR12` > `HDR10+` > `HDR10` > `HLG` > `SDR`)
1552 - `channels`: The number of audio channels
1553 - `tbr`: Total average bitrate in KBit/s
1554 - `vbr`: Average video bitrate in KBit/s
1555 - `abr`: Average audio bitrate in KBit/s
1556 - `br`: Equivalent to using `tbr,vbr,abr`
1557 - `asr`: Audio sample rate in Hz
1558
1559 **Deprecation warning**: Many of these fields have (currently undocumented) aliases, that may be removed in a future version. It is recommended to use only the documented field names.
1560
1561 All fields, unless specified otherwise, are sorted in descending order. To reverse this, prefix the field with a `+`. E.g. `+res` prefers format with the smallest resolution. Additionally, you can suffix a preferred value for the fields, separated by a `:`. E.g. `res:720` prefers larger videos, but no larger than 720p and the smallest video if there are no videos less than 720p. For `codec` and `ext`, you can provide two preferred values, the first for video and the second for audio. E.g. `+codec:avc:m4a` (equivalent to `+vcodec:avc,+acodec:m4a`) sets the video codec preference to `h264` > `h265` > `vp9` > `vp9.2` > `av01` > `vp8` > `h263` > `theora` and audio codec preference to `mp4a` > `aac` > `vorbis` > `opus` > `mp3` > `ac3` > `dts`. You can also make the sorting prefer the nearest values to the provided by using `~` as the delimiter. E.g. `filesize~1G` prefers the format with filesize closest to 1 GiB.
1562
1563 The fields `hasvid` and `ie_pref` are always given highest priority in sorting, irrespective of the user-defined order. This behaviour can be changed by using `--format-sort-force`. Apart from these, the default order used is: `lang,quality,res,fps,hdr:12,vcodec:vp9.2,channels,acodec,size,br,asr,proto,ext,hasaud,source,id`. The extractors may override this default order, but they cannot override the user-provided order.
1564
1565 Note that the default has `vcodec:vp9.2`; i.e. `av1` is not preferred. Similarly, the default for hdr is `hdr:12`; i.e. dolby vision is not preferred. These choices are made since DV and AV1 formats are not yet fully compatible with most devices. This may be changed in the future as more devices become capable of smoothly playing back these formats.
1566
1567 If your format selector is `worst`, the last item is selected after sorting. This means it will select the format that is worst in all respects. Most of the time, what you actually want is the video with the smallest filesize instead. So it is generally better to use `-f best -S +size,+br,+res,+fps`.
1568
1569 **Tip**: You can use the `-v -F` to see how the formats have been sorted (worst to best).
1570
1571 ## Format Selection examples
1572
1573 ```bash
1574 # Download and merge the best video-only format and the best audio-only format,

1583 $ yt-dlp
1584
1585 # Download the best video-only format and the best audio-only format without merging them

1692 ```
1693
1694 # MODIFYING METADATA
1695
1696 The metadata obtained by the extractors can be modified by using `--parse-metadata` and `--replace-in-metadata`
1697
1698 `--replace-in-metadata FIELDS REGEX REPLACE` is used to replace text in any metadata field using [python regular expression](https://docs.python.org/3/library/re.html#regular-expression-syntax). [Backreferences](https://docs.python.org/3/library/re.html?highlight=backreferences#re.sub) can be used in the replace string for advanced use.
1699
1700 The general syntax of `--parse-metadata FROM:TO` is to give the name of a field or an [output template](#output-template) to extract data from, and the format to interpret it as, separated by a colon `:`. Either a [python regular expression](https://docs.python.org/3/library/re.html#regular-expression-syntax) with named capture groups, a single field name, or a similar syntax to the [output template](#output-template) (only `%(field)s` formatting is supported) can be used for `TO`. The option can be used multiple times to parse and modify various fields.
1701
1702 Note that these options preserve their relative order, allowing replacements to be made in parsed fields and viceversa. Also, any field thus created can be used in the [output template](#output-template) and will also affect the media file's metadata added when using `--embed-metadata`.
1703
1704 This option also has a few special uses:
1705
1706 * You can download an additional URL based on the metadata of the currently downloaded video. To do this, set the field `additional_urls` to the URL that you want to download. E.g. `--parse-metadata "description:(?P<additional_urls>https?://www\.vimeo\.com/\d+)` will download the first vimeo video found in the description
1707
1708 * You can use this to change the metadata that is embedded in the media file. To do this, set the value of the corresponding field with a `meta_` prefix. For example, any value you set to `meta_description` field will be added to the `description` field in the file - you can use this to set a different "description" and "synopsis". To modify the metadata of individual streams, use the `meta<n>_` prefix (e.g. `meta1_language`). Any value set to the `meta_` field will overwrite all default values.
1709
1710 **Note**: Metadata modification happens before format selection, post-extraction and other post-processing operations. Some fields may be added or changed during these steps, overriding your changes.
1711
1712 For reference, these are the fields yt-dlp adds by default to the file metadata:
1713
1714 Metadata fields | From
1715 :--------------------------|:------------------------------------------------
1716 `title` | `track` or `title`
1717 `date` | `upload_date`
1718 `description`, `synopsis` | `description`
1719 `purl`, `comment` | `webpage_url`
1720 `track` | `track_number`
1721 `artist` | `artist`, `creator`, `uploader` or `uploader_id`
1722 `genre` | `genre`
1723 `album` | `album`
1724 `album_artist` | `album_artist`
1725 `disc` | `disc_number`
1726 `show` | `series`
1727 `season_number` | `season_number`
1728 `episode_id` | `episode` or `episode_id`
1729 `episode_sort` | `episode_number`
1730 `language` of each stream | the format's `language`
1731
1732 **Note**: The file format may not support some of these fields
1733
1734
1735 ## Modifying metadata examples
1736
1737 ```bash
1738 # Interpret the title as "Artist - Title"
1739 $ yt-dlp --parse-metadata "title:%(artist)s - %(title)s"
1740
1741 # Regex example
1742 $ yt-dlp --parse-metadata "description:Artist - (?P<artist>.+)"
1743
1744 # Set title as "Series name S01E05"
1745 $ yt-dlp --parse-metadata "%(series)s S%(season_number)02dE%(episode_number)02d:%(title)s"
1746
1747 # Prioritize uploader as the "artist" field in video metadata
1748 $ yt-dlp --parse-metadata "%(uploader|)s:%(meta_artist)s" --embed-metadata
1749
1750 # Set "comment" field in video metadata using description instead of webpage_url,
1751 # handling multiple lines correctly
1752 $ yt-dlp --parse-metadata "description:(?s)(?P<meta_comment>.+)" --embed-metadata
1753
1754 # Do not set any "synopsis" in the video metadata
1755 $ yt-dlp --parse-metadata ":(?P<meta_synopsis>)"
1756
1757 # Remove "formats" field from the infojson by setting it to an empty string
1758 $ yt-dlp --parse-metadata ":(?P<formats>)" -j
1759
1760 # Replace all spaces and "_" in title and uploader with a `-`
1761 $ yt-dlp --replace-in-metadata "title,uploader" "[ _]" "-"
1762
1763 ```
1764
1765 # EXTRACTOR ARGUMENTS
1766
1767 Some extractors accept additional arguments which can be passed using `--extractor-args KEY:ARGS`. `ARGS` is a `;` (semicolon) separated string of `ARG=VAL1,VAL2`. E.g. `--extractor-args "youtube:player-client=android_embedded,web;include_live_dash" --extractor-args "funimation:version=uncut"`
1768
1769 Note: In CLI, `ARG` can use `-` instead of `_`; e.g. `youtube:player-client"` becomes `youtube:player_client"`
1770
1771 The following extractors use this feature:
1772
1773 #### youtube
1774 * `lang`: Prefer translated metadata (`title`, `description` etc) of this language code (case-sensitive). By default, the video primary language metadata is preferred, with a fallback to `en` translated. See [youtube.py](https://github.com/yt-dlp/yt-dlp/blob/c26f9b991a0681fd3ea548d535919cec1fbbd430/yt_dlp/extractor/youtube.py#L381-L390) for list of supported content language codes
1775 * `skip`: One or more of `hls`, `dash` or `translated_subs` to skip extraction of the m3u8 manifests, dash manifests and [auto-translated subtitles](https://github.com/yt-dlp/yt-dlp/issues/4090#issuecomment-1158102032) respectively
1776 * `player_client`: Clients to extract video data from. The main clients are `web`, `android` and `ios` with variants `_music`, `_embedded`, `_embedscreen`, `_creator` (e.g. `web_embedded`); and `mweb` and `tv_embedded` (agegate bypass) with no variants. By default, `android,web` is used, but `tv_embedded` and `creator` variants are added as required for age-gated videos. Similarly, the music variants are added for `music.youtube.com` urls. You can use `all` to use all the clients, and `default` for the default clients.
1777 * `player_skip`: Skip some network requests that are generally needed for robust extraction. One or more of `configs` (skip client configs), `webpage` (skip initial webpage), `js` (skip js player). While these options can help reduce the number of requests needed or avoid some rate-limiting, they could cause some issues. See [#860](https://github.com/yt-dlp/yt-dlp/pull/860) for more details
1778 * `comment_sort`: `top` or `new` (default) - choose comment sorting mode (on YouTube's side)

1833 # PLUGINS
1834
1835 Note that **all** plugins are imported even if not invoked, and that **there are no checks** performed on plugin code. **Use plugins at your own risk and only if you trust the code!**
1836
1837 Plugins can be of `<type>`s `extractor` or `postprocessor`.
1838 - Extractor plugins do not need to be enabled from the CLI and are automatically invoked when the input URL is suitable for it.
1839 - Extractor plugins take priority over builtin extractors.
1840 - Postprocessor plugins can be invoked using `--use-postprocessor NAME`.
1841
1842
1843 Plugins are loaded from the namespace packages `yt_dlp_plugins.extractor` and `yt_dlp_plugins.postprocessor`.
1844
1845 In other words, the file structure on the disk looks something like:
1846
1847 yt_dlp_plugins/
1848 extractor/
1849 myplugin.py
1850 postprocessor/
1851 myplugin.py
1852
1853 yt-dlp looks for these `yt_dlp_plugins` namespace folders in many locations (see below) and loads in plugins from **all** of them.
1854
1855 See the [wiki for some known plugins](https://github.com/yt-dlp/yt-dlp/wiki/Plugins)
1856
1857 ## Installing Plugins
1858
1859 Plugins can be installed using various methods and locations.
1860
1861 1. **Configuration directories**:
1862 Plugin packages (containing a `yt_dlp_plugins` namespace folder) can be dropped into the following standard [configuration locations](#configuration):
1863 * **User Plugins**
1864 * `${XDG_CONFIG_HOME}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Linux/macOS)
1865 * `${XDG_CONFIG_HOME}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1866 * `${APPDATA}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Windows)
1867 * `${APPDATA}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1868 * `~/.yt-dlp/plugins/<package name>/yt_dlp_plugins/`
1869 * `~/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1870 * **System Plugins**
1871 * `/etc/yt-dlp/plugins/<package name>/yt_dlp_plugins/`
1872 * `/etc/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1873 2. **Executable location**: Plugin packages can similarly be installed in a `yt-dlp-plugins` directory under the executable location:
1874 * Binary: where `<root-dir>/yt-dlp.exe`, `<root-dir>/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1875 * Source: where `<root-dir>/yt_dlp/__main__.py`, `<root-dir>/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1876
1877 3. **pip and other locations in `PYTHONPATH`**
1878 * Plugin packages can be installed and managed using `pip`. See [yt-dlp-sample-plugins](https://github.com/yt-dlp/yt-dlp-sample-plugins) for an example.
1879 * Note: plugin files between plugin packages installed with pip must have unique filenames.
1880 * Any path in `PYTHONPATH` is searched in for the `yt_dlp_plugins` namespace folder.
1881 * Note: This does not apply for Pyinstaller/py2exe builds.
1882
1883
1884 `.zip`, `.egg` and `.whl` archives containing a `yt_dlp_plugins` namespace folder in their root are also supported as plugin packages.
1885 * e.g. `${XDG_CONFIG_HOME}/yt-dlp/plugins/mypluginpkg.zip` where `mypluginpkg.zip` contains `yt_dlp_plugins/<type>/myplugin.py`
1886
1887 Run yt-dlp with `--verbose` to check if the plugin has been loaded.
1888
1889 ## Developing Plugins
1890
1891 See the [yt-dlp-sample-plugins](https://github.com/yt-dlp/yt-dlp-sample-plugins) repo for a template plugin package and the [Plugin Development](https://github.com/yt-dlp/yt-dlp/wiki/Plugin-Development) section of the wiki for a plugin development guide.
1892
1893 All public classes with a name ending in `IE`/`PP` are imported from each file for extractors and postprocessors repectively. This respects underscore prefix (e.g. `_MyBasePluginIE` is private) and `__all__`. Modules can similarly be excluded by prefixing the module name with an underscore (e.g. `_myplugin.py`).
1894
1895 To replace an existing extractor with a subclass of one, set the `plugin_name` class keyword argument (e.g. `class MyPluginIE(ABuiltInIE, plugin_name='myplugin')` will replace `ABuiltInIE` with `MyPluginIE`). Since the extractor replaces the parent, you should exclude the subclass extractor from being imported separately by making it private using one of the methods described above.
1896
1897 If you are a plugin author, add [yt-dlp-plugins](https://github.com/topics/yt-dlp-plugins) as a topic to your repository for discoverability.
1898
1899 See the [Developer Instructions](https://github.com/yt-dlp/yt-dlp/blob/master/CONTRIBUTING.md#developer-instructions) on how to write and test an extractor.
1900
1901 # EMBEDDING YT-DLP
1902
1903 yt-dlp makes the best effort to be a good command-line program, and thus should be callable from any programming language.
1904
1905 Your program should avoid parsing the normal stdout since they may change in future versions. Instead they should use options such as `-J`, `--print`, `--progress-template`, `--exec` etc to create console output that you can reliably reproduce and parse.
1906
1907 From a Python program, you can embed yt-dlp in a more powerful fashion, like this:
1908
1909 ```python
1910 from yt_dlp import YoutubeDL
1911
1912 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
1913 with YoutubeDL() as ydl:
1914 ydl.download(URLS)
1915 ```
1916
1917 Most likely, you'll want to use various options. For a list of options available, have a look at [`yt_dlp/YoutubeDL.py`](yt_dlp/YoutubeDL.py#L184).
1918
1919 **Tip**: If you are porting your code from youtube-dl to yt-dlp, one important point to look out for is that we do not guarantee the return value of `YoutubeDL.extract_info` to be json serializable, or even be a dictionary. It will be dictionary-like, but if you want to ensure it is a serializable dictionary, pass it through `YoutubeDL.sanitize_info` as shown in the [example below](#extracting-information)
1920
1921 ## Embedding examples
1922
1923 #### Extracting information
1924
1925 ```python
1926 import json
1927 import yt_dlp
1928
1929 URL = 'https://www.youtube.com/watch?v=BaW_jenozKc'
1930
1931 # ℹ️ See help(yt_dlp.YoutubeDL) for a list of available options and public functions
1932 ydl_opts = {}
1933 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
1934 info = ydl.extract_info(URL, download=False)
1935
1936 # ℹ️ ydl.sanitize_info makes the info json-serializable
1937 print(json.dumps(ydl.sanitize_info(info)))
1938 ```
1939 #### Download using an info-json
1940
1941 ```python
1942 import yt_dlp
1943
1944 INFO_FILE = 'path/to/video.info.json'
1945
1946 with yt_dlp.YoutubeDL() as ydl:
1947 error_code = ydl.download_with_info_file(INFO_FILE)
1948
1949 print('Some videos failed to download' if error_code
1950 else 'All videos successfully downloaded')
1951 ```
1952
1953 #### Extract audio
1954
1955 ```python
1956 import yt_dlp
1957
1958 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
1959
1960 ydl_opts = {
1961 'format': 'm4a/bestaudio/best',
1962 # ℹ️ See help(yt_dlp.postprocessor) for a list of available Postprocessors and their arguments
1963 'postprocessors': [{ # Extract audio using ffmpeg
1964 'key': 'FFmpegExtractAudio',
1965 'preferredcodec': 'm4a',
1966 }]
1967 }
1968
1969 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
1970 error_code = ydl.download(URLS)
1971 ```
1972
1973 #### Filter videos
1974
1975 ```python
1976 import yt_dlp
1977
1978 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
1979
1980 def longer_than_a_minute(info, *, incomplete):
1981 """Download only videos longer than a minute (or with unknown duration)"""
1982 duration = info.get('duration')
1983 if duration and duration < 60:
1984 return 'The video is too short'
1985
1986 ydl_opts = {
1987 'match_filter': longer_than_a_minute,
1988 }
1989
1990 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
1991 error_code = ydl.download(URLS)
1992 ```
1993
1994 #### Adding logger and progress hook
1995
1996 ```python
1997 import yt_dlp
1998
1999 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2000
2001 class MyLogger:
2002 def debug(self, msg):
2003 # For compatibility with youtube-dl, both debug and info are passed into debug
2004 # You can distinguish them by the prefix '[debug] '
2005 if msg.startswith('[debug] '):
2006 pass
2007 else:
2008 self.info(msg)
2009
2010 def info(self, msg):
2011 pass
2012
2013 def warning(self, msg):
2014 pass
2015
2016 def error(self, msg):
2017 print(msg)
2018
2019
2020 # ℹ️ See "progress_hooks" in help(yt_dlp.YoutubeDL)
2021 def my_hook(d):
2022 if d['status'] == 'finished':
2023 print('Done downloading, now post-processing ...')
2024
2025
2026 ydl_opts = {
2027 'logger': MyLogger(),
2028 'progress_hooks': [my_hook],
2029 }
2030
2031 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
2032 ydl.download(URLS)
2033 ```
2034
2035 #### Add a custom PostProcessor
2036
2037 ```python
2038 import yt_dlp
2039
2040 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2041
2042 # ℹ️ See help(yt_dlp.postprocessor.PostProcessor)
2043 class MyCustomPP(yt_dlp.postprocessor.PostProcessor):
2044 def run(self, info):
2045 self.to_screen('Doing stuff')
2046 return [], info
2047
2048
2049 with yt_dlp.YoutubeDL() as ydl:
2050 # ℹ️ "when" can take any value in yt_dlp.utils.POSTPROCESS_WHEN
2051 ydl.add_post_processor(MyCustomPP(), when='pre_process')
2052 ydl.download(URLS)
2053 ```
2054
2055
2056 #### Use a custom format selector
2057
2058 ```python
2059 import yt_dlp
2060
2061 URL = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2062
2063 def format_selector(ctx):
2064 """ Select the best video and the best audio that won't result in an mkv.
2065 NOTE: This is just an example and does not handle all cases """
2066
2067 # formats are already sorted worst to best
2068 formats = ctx.get('formats')[::-1]
2069
2070 # acodec='none' means there is no audio
2071 best_video = next(f for f in formats
2072 if f['vcodec'] != 'none' and f['acodec'] == 'none')
2073
2074 # find compatible audio extension
2075 audio_ext = {'mp4': 'm4a', 'webm': 'webm'}[best_video['ext']]
2076 # vcodec='none' means there is no video
2077 best_audio = next(f for f in formats if (
2078 f['acodec'] != 'none' and f['vcodec'] == 'none' and f['ext'] == audio_ext))
2079
2080 # These are the minimum required fields for a merged format
2081 yield {
2082 'format_id': f'{best_video["format_id"]}+{best_audio["format_id"]}',
2083 'ext': best_video['ext'],
2084 'requested_formats': [best_video, best_audio],
